SPECIFICATION forming part of Letters Patent No. 379,365, dated March 13, 1888.

Application filed Dcr'emhcrll, 1865. Serial No. 186,256. (Model) To all whom, 7'2 may concern Be it known that I, WILLIAM M. CLARK, of Boscobcl, in the county of Grant and St-ate of W'isconsimhave invented a new and Improved Twine Grain-Binder, ofwhich the following is a full, clear, and exact description.

This invention relates to certain new and useful improvements in twine grain-binders; and the object of my invention is to simplify the'construetion and make the machine compact and the operation more simple.

The invention consists in the construction and combination of numerous parts and de tails, as will be fully described and set forth hereinafter, and then pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification,

' in which similar letters of reference indicate corresponding parts in all the figures.

the frame, uniting the brackets, which bars A are united at their free ends by a cross-bar, A. On the base-frame a platform, A is secured, which is curved, as shown in Fig. l, and down which the grain to be bound slides, the grain being delivered upon the said platform by the reaper to which the binder is attached. The said platform A has a slot, A, Fig. 4, through which the needle can pass. A flat crosspiece, A is provided below the platform A, and has a slot corresponding to the slot in the platform A A laterally-swinging plate, A, (shown partly in full and partlyin dotted lines in Fig. 5,) is pivoted by the pivot A and is adapted to swing directly under the piece A and to close the slot in the same, to prevent dirt. &c., from passing through said slot into the lower part of the machine. A rod, A", is pivoted to the swinging plate A and guided in an eye, A", on one of the crossbars, A, of

the frame of the machine. A spiral spring, A, surrounds the rod A between the guide A and a cross pin, A, on the said rod A. The needle, when it enters the slot in the platform, acts on the edge a of thelaterally-swinging plate A and presses the same toward the right, Fig. 5, whereby the spring A is compressed, and when the needle leaves the slot the spring A expands and throws the plate A under the slot again. The said laterallyswinging plate is also shown in Figs. 1 and 4..

In the cross pieces A and A of themachine the four shafts B, D, F, and H- are journaled. On that end of the shaft B projecting beyond the crosspiece A a crank, B, is mounted, on the free end of which a curved lever, B is pivoted about one fourth of the length of said lever from its lower end. To the upper end of said curved lever B an arm, B is pivoted,

which carries on its free end a pin, B", provided with a roller which runs in a longitudinal slot, B extending from side to side in the cross bar A. To the lower end of the curved lever 13 two tines or teeth, 13, are pivoted, one on each side, the said tines being pivoted at about the middle of their length.

They are pointed at their lower ends, and theirv outer edges are concave directly above the points, and their inner edges, or the edges facing the harvester, are convex, as is shown in Figs. 1 and 4. The upper-ends of the tines B are united by across-pin and roller or spool, B against which the free end of a spring, B rests, which has-its other end secured in the lower end of the curved lever B and thereby the upper ends of the tines are pressed against the inner angle of the lever B".

On the outer end of the cross-piece A a short shaft, 0, is journaled, to the outer end of which a quadrant runner or guide, O, is secured, which is curved from the inner end of the cross-piece A downward and toward the longitudinal central plane of the machine, and is provided on its free end with an upwardly-projecting arm, 0 which is curved more or less and passed into a pocket, O, on the outer side of the cross piece A, which pocket is open at the bottom and closed at the top. The arm O is provided at its upper end with a cross-pin, (3*, within the pocket, which cross pin is of such size that when the runner or guide 0 is lowered as much as is necessary the said cross-pin O strikes a stop at the bottom of the pocket 0" and prevents the further descent of the guide 0.

On that end of the shaft O projecting from the inner side of the cross-piece A" the arm O is mounted, which projects into an upright hollow casing, O, on one of the longitudinal top bars, A, the said casing having a vertical slot through which the end of the arm O can pass. Aspiral spring, 0 is held between the top of the casing and the end of the arm 0 and presses the end of the arm 0 downward, thereby pressing the guide 0 downward, as said guide is rigidly mounted on the end of the shaft O. The inner end of the shaft O is preferably j ournaled in a bracket, 0 projecting from the top longitudinal bar, A so as to give the shaft more stability.

On the end of the shaft D an arm, D, is secured, and to the end of said arm D the needle D is pivoted at or near the center of the length of said needle. The upper end of the needle is pivoted to a connecting-bar, D, which in turn is pivoted to the cross-bar A", or a projection of the same. The needle is provided at its lower end with a lug, D, projecting from the inner side, and in said lug D* an eye, D is formed, through which the twine E is passed. A guideeye, D, is formed on the side of the needle D near the upper end of the same. A guide-eye, D is secured on the outer side of the connecting-bar D, and a twine-guide, D is formed on the upper end of a piece, D secured on the crossbar A. The twine E is held in the twinebox D", and passes from the same through an eye, D, on a standard, D, the guide-eyes D and D and the eye D A sliding hook, D is passed through a vertical slot in the standard D and is passed th rough a standard, D. A spiral spring, D, surrounds the sliding hook D bet ween the standard D and a nut,D screwed on the outer threaded end of the hook D, by means of which nut the tension can be regulated. The spring presses the prong of the hook against the twine E as it passes through the guide D and thus keeps the twine at the desired tension. This tension can be regulated by regulating the spring D On the end of the shaft F is the ejector, which consists of an ejectorarm, F, secured rigidly on the end of said shaft F, and a compressor and trip, F is also mounted loosely on said shaft. A bar, F is pivoted on the compressor and trip F passes through a slot on the upper end of the ejector F, and is provided on its end with a cross-pin, F*. A spiral'spring, F is coiled around the bar F between the pivotal end ofsaid bar and the upper end of the ejector F, which spring presses the compressor and trip F toward the ejector F. A cam, G, is loosely mounted on the shaft F, but is rigidly connected with the conr pressor and trip F so asto movewith thesame, which cam is outside of the crossbar A*. On said cam an arm, H, rests, which is rigidly mounted on the end of the shaft H. On the opposite end of the shaft H an angular arm, H is mounted rigidly,which is provided with a downwardly-projecting lug, H at its outer end, having an aperture, H, through which a rod, H passes, which is pivoted on the end piece, I, of the machine, and is surrounded by a spiral spring, H acting against the end of said lug H and thereby pressing the lever H downward. The arm H is provided on its free end with a downwardly-projectinglug or point, H at theupper end of which is formed an upwardly-projecting beveled lug, H", which is stepped to form a shoulder, H, and a lug, H, which has a beveled top, Ht", between the inner end of which beveled top and the said arm H a recess, H, is formed, all as is shown in detail in Fig. 17.

A forked lever, 1, Figs. 3, 6, and 7, is pivoted on one of the top bars of the machineframe to swing laterally, and in its forked end is held the clutch-sleeve I", having an annular groove, 1 into which pins Pon the prongs of the fork pass, which clutchsleeve also has two clutch ends, I and 1 The clutch-sleeve is mounted to slide on a shaft, J, carrying at its outer end a sprocket-wheel, J, over which the driving-chain is passed. On said shaft J a cog-wheel, J", is mounted, which is provided with a clutch-collar, J adapted to engage with the clutch end 1 of thesleeve I". On the end of the shaft B aclutch-sleeve, I, is rigidly mounted, the end of which is adapted to engage with the end 1" of the clutchsleeve I and in said clutch-sleeve 1 the end of the shaft J is mounted to turn. A pin, 1", is passed through the sleeve I and through a longi tudinal slot in the shaft J, so as to permit of sliding the clutchsleeve l" on the shaft J, and at the same time causing the sleeve to revolve with the shaft J. To the lever l alatch, I, is pivoted, which can drop into the notch or recess H of the arm H for locking said arm in place. A latch, J", is pivoted on the crosspiece A and is provided with a hook adapted to pass into a notch, 1 in the inner side of the lever 1, as shown in Figs. 6 and 7,which latch also engages with the lug H of lever H An angle-lever, K, is pivoted on one of the top bars, A, one end of which is provided with a spring-arm, K, which rests against the side of the lever I, Fig. 3. An arm, K is rigidly secured on the shaft H, and projects downward in such a manner that its lower end is in con tact with the other arm of the angle-lever K, as shown in Fig. 1.

On the shaft L,journaled in the end piece or bracket, I, and in an intermediate crosspiece of the machine, a cog-wheel, L, is mounted, which engages with the above-mentioned cog-wheel J on the shalt J. A cam-wheel, L", having the same diameter as the cog wheel L, is rigidly mounted on the shaft L. Said cam-wheel is provided with arecess, L at one end of which a projection, L, is formed, whioh,however, does not project out of the plane of the wheel L and at the other end of the recess the pin L projects from the inner surface of said wheel.

On that end of the shaft F opposite the one on which the ejector is mounted the cam M is mounted, on the wider end of which asegmeir tal rack, M, is formed, which engages with a segmental rack, M", formed on the edge of a short lever,- M pivoted on a pin, M on the inner surface of the end piece, I. V The pin L and cam M lie in the same plane, while the projection L and lever M lie in a difierent plane from that of the former parts. The wheel L revolves in the direction of the arrow a, Fig. 10, the wheel L being revolved by the cogwheel J on the shaft J and the wheel L revolving with the wheel L. Vheu the wheel revolves, the pin L strikes the cam M and swings the same in the direction of the arrow [1, Fig. 10, whereby the shaft F, on which the cam M is mounted, is thrown in such a manner as to swing the arm F of the ejector in the direction of the arrow 0, Figs. 1 and at. The cam M is finally brought into the position shown in Fig. 11, and as the wheel L continues to revolve. the projection L at that end of the recess L opposite the one at which the pin L is located strikes the lever M and swings the same in the direction of the arrow (1, Fig. 11, whereby the cam M is swung in the inverse direction of the arrow b as the segmental rack on the end of the lever M engaged with the segmental rack on the end of the cam hi, and thus the cam M is brought back into the position it had, as shown in Fig. 10, in which position it remains until the cam wheel L has made another revolution, when the pin L again strikes the cam and the ejector is again operated, and so on.

On that end of the shaft D opposite the one on which the arm D is secured a cam-arm, N, is formed, which is provided with a lateral projection, N, having a slot, N On the shaft L a cam. O, is mounted, which is provided with a prong, O, at one side of arccess, 0 formed in the cam O. A lever, 0 is pivoted on the frame of the machine, and is provided at its upper end with apin, 0*, which passes into the slot N of the arm N. Said lever O is provided on its lower end with a cam projection, which is on the side of the lever 0 A can], O, is rigidly mounted on the shaft L adjacent to the cam 0. When the cam O revolves in the direction of the arrow a Fig. 8, which is the same as the direction of the arrow a, Fig. 10, the prong O strikes the end of the cam-arm N and swings thesaid camarm in the direction of the arrow 6, Fig. 8, whereby the shaft D is turned in the corresponding direction, and the arm D and the needle D are swung down and remain lowered, as shown in dotted lines in Fig. 9, until the cam edge of the cam O runs off of the cam-arm N. The cam 0 then begins to act on the cam O of the lever O andpresses the said lever O in the direction of the arrow f, Fig. 9, causing the pin 0* on the end of said lever O, which pin worksin the slot N to swing the camarm N in the reverse direction of the arrow 0, whereby the shaft D is turned in such adirection as to cause the arm D to swing upward, whereby the needle D is raised.

On the shaft L cams P and Q are mounted, of which the former, P, has the prong P, the prong P and the shoulder P". The cam Q has the corner Q and the shoulder or corner Q and the straight part Q. (Jam-levers R and S are pivoted on the frame, and are provided with the circular recesses or openings R and S. The lever B is provided with two diametrically opposite beveled projections, R and it, on the inner edges of the recess, as is shown in Figs. 6, 7, and 16. The lever B is provided with a recess, R*, in each surface, said recesses being formed in opposite faces.

" The recess It at the right-hand edge of the lever is in the outer face, and the recess at the left-hand edge is on the inner surface, as shown in Fig. 16. The oainsPand Qare also in different planes, as is shown in Fig. 15. The cam Pacts on thclcft-hand part of the lever B; but as the right-hand part is recessed in the outer surface the cam P can swing through said recess without acting on the lever. The cam Q acts onthe right-hand part of thelever R, but does not act on the left-hand part, as the cam can swing through the recess R in the left- When the cams are revolved in hand part.

the direction of the arrow (0, (corresponding to the direction of the arrow a in Figs. 8 and 9 and u. in Figs. 10 and ll,) the parts P and P acting on the left-hand part of the lever B, swing the same in the direction of the ar- IIS row During this time the cam Q passes through the left-hand recess, as shown in dotted lines, without acting. As the revolution in the direction of the arrow a continues, the cam Q begins to act on the right-hand part of the lever B and swings the lever It in the inverse direction of the arrow g, whereby the lever B is reciprocated. As shown in Fig. 6, the cam Q is moving the lever It in the in verse direction of the arrow and is acting on the projection R? at the right, and the projection R at the left rests against the cam P. As shown in Fig. 7, the cam P is swinging the lever B in the direction of the arrow 9 and has almost completed its stroke. WVhen the stroke is completed, the projection R of the lever snaps into the recess formed between the prong-P and the projection or part P of the cam P. These shoulders and projections are formed in the cams for the purpose of having positive motion at all times-thatis, the lever cannot swing or play in the inverse direction of that in which it is being moved. For example, in Fig. 6 the lever cannot be moved to the right-that is, in the direction of the arrow gas the projection R rests against the cam P, and it can be moved in the inverse direction g the proper distance, which is governed by the cam Q, as otherwise it would conflict with the edge of the cam P. The lever S is also recessed at opposite edges and opposite sides, and is acted on by the cams T T, which reciprocate it in the same direction as the lever B is reciprocated-that is, the projection T swings it to the right and the projection T swings it to the left, and so on. The lower end of the lever B is passed into an aperture in a lever, U, pivoted on the bracket on one end piece, A, of the machine, which lever U swings in the horizontal plane and passes through a slot, If, in the bracket or supporting-piece A. A fork, U, is formed on the swinging end of the lever U, and a segmental rack, U is secured on the ends of the prongs, which rack engages with a cog-wheel, V, mounted rigidly on a tubular spindle, V, mounted in a frame, U projecting downward from a cross piece, A, of the machine. Through the tubular spindle a spindle, V projects, which is provided with pins V passing through longitudinal slotsV*in the spindle V. The spindle V is surrounded by a spiral spring, V between the lower end of the spindle V and a cross-piece, V 'on the end of the spindle V On the upper end of the spindle V the knotting hook or jaw V is formed, and on the upper end of the spindle V the knotting hook orjaw V is formed, which is above the hook V The hooks or jaws V and V have notches in their inner edges short distances from the ends. The lower end of the spindle V rests upon a lever, vV, pivoted on an arm, W, extending downward from the crosspiece A, Fig. 4, of the frame. From the arm \V a pin, NV projects, against which the upper end of the lever W can strike, which pin is so located that the lever WV has slight play. A lug, W projects downward from the rack U at one end of the same, and to said lug a track-lever, WV, is pivoted, which has its end slightly beveled. The free end of this rests upon a pin, W, projecting laterally from an arm, \V, secured to and project ing downward from the rack U On the top of the lever \V a cam-piece, X, is formed, which is inclined upward and beyond the end of said lever. in the side adjacent to the spindle V it is provided with a recess, X, and on the other side it is provided with a laterally-projecting beveled lug, X", Fig. 1. The rack U runs over a hook lng, U", projecting downward from the frame U for the purpose of preventing the rack from sagging.

A lever,Y, is pivoted on the cross-piece A, and is provided at one end with aslot, Y, into which the lower end of the cam-levers passes. The free end Y of the lever Y is bent over in front of the rack U and terminates in a hook, Y, provided on its top with a recess or notch, Y, for receiving the knife Z, projecting from the supporting-frame U Two lugs, Z Z*, project from the supporting-frame U directly below the knife Z, the upper lug, Z, being shorter than thelower lug, Z", and a notch, Z, is formed between them. The hook Y on the end of the lever Y is also provided with a groove, Y in its inner side, as shown in detail in Fig. 18. A lug, 1', provided with a verticalV-shaped groove, 8. projects upward from the supporting-frame U. The lug hasits bottom recessed to permit a wire or rod. t, secured on the lever, Y, to pass under said lug, as shown in Figs. 5 and 12, which wire has its end bent upward to form a hook, 0. An angle-lever, m, is pivoted on the inner side of the supporting frame U which is provided with a check-pin, m, against which the said lever can strike, which prevents the said lever m from being swung back too far. The lever m is provided on the upper end ofits up wardlyprojecting shank with an arm, n, projecting transversely over the supporting piece A. The wheel J is held in place so that it cannot shift by the forked piece J, Fig. 3.

The operation is as follows: In order to show the operation of the machine more clearly, I will first describe the formation of the bundle, the passing of the twine around the same by the needle, the discharge of the'bundle,-the mechanism for' performing these operations, and then the operation of the mechanism for forming theloop and knot. The shaft J, which carries the sprocket-wheel J, is continually revolved by a chain, belt, or gearing, as may be desired,and revolves the clutchsleeve 1*, which is engaged with the clutchsleeve 1", whereby the shaft B isrevolved in the direction of the arrow a", Fig. 1, whereby the tines or prongs B are moved up and down on a curved line as the bent lever B is reciprocated by the crankarm B on the end of the shaft B, and the said tines are connected with said lever B'. The upper end of the lever is guided by the arm 13*,

the end pin of which runs in the slot B that is, the tines B are moveddown ward in the direction of the guide 0, as indicated by the arrow b Fig. 1. the lower prongs of the tines being slightlybelow the bottom edge of the guide and short distances from the curved platform A The tines catch the grain that slides down the platform A and push it in the direction of the arrow 1) beyond the arm 0 and against the compressor and trip Fh the ejector F being raised, as shown in Fig. 1. The guide 0' can give slightlythat is, it can swing upwardwhereby the arm 0 is swung upward and compresses the spring C in the casing O. Aftcrthe grain has been forced beyond the lower end of the guide, the springin the said casing forces the arm 0 downward again,whereby the swinging end of theguide O is forced downward. The twine E extends from the arm Y upward to the needle D and the grain is forced against the twine, as shown in Fig. 1. This operation is continued until the quantity of grain between the arm 0 and the compressor and trip F is so great as to swing the compressor and trip F in the direc tion of the arrow 0 Fig. 1, whereby the'cam G is rocked and raises the arm H, whereby the shaft- H is revolved in the direction of the arrow (2, Fig. 1. During all this time the clutchsleeve i has been held engaged with the clutch l by the lever l,which inturnislocked in place by the latch Jflthe end of which catches in the recess 1 in the forked laterally-swinging lever 1, in which fork the sleeve 1' is held. Then as the grain is pressed against the triparm F the arm H is raised by the cam G,and the point or prong of the hook H slowly rises out of the notch H of the caurwheel L, and the arm K presses back the clutch-holding lever 1 by means of the bellcrank K. \Vhen a sufficient quantity of grain is packed against the compressor and trip'arm F to raise the prong H of the hook H entirely out of the notch of the cam-wheel L, the spring K is pressed tightly against the clutch holding lever 1. At the same time the shoulder H on the hook Hstrikes the projection of the latch J, beginning to lift said latch, the grain being continually packed against the compressor and trip-arm F until the hook H raises the latch J" wholly out of the notch l in the clutchholding lever l. The latch l is provided with a shoulder or pin that holds the latch the proper height to strike the bevel H on the hook H and latches itself into the notch H of the said hook when the latter is at its highest point. \Vhen the hook H" has been lifted out of the notch in the cam-wheel or to its highest point, or nearly so, by thrprcssu re of the grain upon the trip-arm F the spring K is compressed against the side of the clutch-holding lever I, so that when this is released from the latch J the spring K throws the clutch-holding lever I, carrying the latch 1'', from the clutch operating the packer to the clutch operating the binder,when the latch 1 strikes and slides up .equilibri um. The spring H, surrounding the rod H and pressing against the lug or prong H of the hook H", presses the prong or point H of said hook upon the rim of the cam-wheel A now in action, so that when the notch in the cam-wheel arrives opposite the point or prong H the latter will snap into the said notch, thus arresting further movement of the cam-wheel. The said point or prong H is released from the latch l by the action or expansion of the previouslycompressed spring H overcoming the friction between the latch l and the side of the notch H,which has the effect of rocking the shaft H in the reverse direction of the arrow (P, and thus depressing the hook H carying its point or prong H down into the notch of the cam L, the arm H of the shaft H having been liberated from the cam G. The beveled head of the hook H pressing against the side of the clutch'holding lever I, instantly throws it toward the beak of the latch J and the clutch-sleeve I into engagement with the clutch 1 the beak of said latch dropping into the notch l of the clutch-holding lever 1, thus. effectually securing the engagement of the clutch-sleeve I with the clutch I, which latter operation of parts, however, is preceded by the action of certain other parts, which will presently be described. Before the beveled lug H of the prong or point H of the hook H strikes or acts in its descent upon the clutch-holding lever I, as the said prong or point is about to enter the notch in the cam-wheel L, said hook releases itself from the latch I as above described. As the wheel J is revolved it revolves the wheel L in the direction of the arrow a, Figs. 10 and 11, and to", Figs. 8 and 9, these arrows indicating the same direction, as the drawings face in different directions. The prong O of the cam O strikes the cam-arm N on the end of the shaft D and swings said cam in the direction of the arrow 6, Fig. 8, whereby the needle D is swung down in the direction of the arrow 0, Fig. l, and the twine is caught by the hook 0 on the end of the wire it in a manner that will be set forth hereinafter, and a loop is formed around the bundle of grain, as shown in Fig. 4. The thread is then cut in a manner that will be set forth hereinafter. The needle remains lowered as the end of the cam N runs around the greater part of the rim of the cam 0. As the cam N runs over the edge of the cam O the cam O strikes the cam O on the lever O and forces said lever O in the direction of the arrowf, Fig. 9, causing the pin 0 on the end of the lever O to swing the cam N on the shaft D in the inverse direc- ITS tion of the arrow 6', whereby the needle D is raised again. During the time that the needle is lowered the pin L of the wheel L strikes the cam M, Fig. 10, and swings the same in the direction of the arrow 6, whereby the shaft F is turned in such a manner as to throw the ejector F and compressor and trip F in the direction of the arrow 0 Fig. 4, causing said ejector to throw the bundle out of the machine. By the movements given to the cam M by the pin L the arm 3' 3 is swung down to the position shown in Fig. 11. Immediately after the pin 1Y has struck the cam M the projection L* of the wheel L strikes the arm M and swings the same in the direction of the arrow 61, whereby the cam M is swung in the inverse direction of the arrow 1), and thereby the shaft F is turned in such a direction as to swing the ejector back into the normal position until the wheel L makes another revolution, the pin L strikes the cam M, and another bundle is ejected. In Fig. 10 the ejector is shown in the normal position in dotted lines. and in Fig. 11 it is shown in the position it holds after it has thrown the bundle.

The operation of forming the knot is as follows: During the time that the grain is being packed between the arm 0' and the arm F the twine E is held in the position shown in Fig. 1, the end of the twine being held below the knife Z and between the lugs Z and Z and in the recess Z, between which lugs it is pressed by the hook Y The angle-lever m is in the position shown in Fig. 1, and the hook o is some distance from the block r. As stated, the needle D moves downward into the position shown in Fig. 4, whereby the twine is carried downward. Immediately after the needle has been lowered the rack U begins to swing in the direction of the arrow g Fig. 5, and strikes the lower end of the lever m,thereby swinging the upper end and the prong n of the same in the direction of the arrow h", Fig. 1, and throwing the part E, Fig. 1, of the twine E in the inverse direction of the arrow 0', so that it will be against that part of the twine which has been carried down by the needle D. The wheel V is now revolved by the rack U", whereby the two jaws V and V are revolved and form a loop, the twine forming the loop passing around the outside of both of said jaws. The cam-lever S nowswings the lever Y in the direction of the arrow Fig. 5, whereby the hook Y is moved toward the left, Fig. 1, and the rod t is moved in the same direction, and the hook 0 on the end of said rod catches both strands of the twine and pulls the same into the block a, as shown in Fig. 4. As soon as the rack U begins to swing in the direction of the arrow Fig. 5, the beveled end of the track-lever W" strikes the under side of the bevel X of the cam X, and thus pushes said cam X and the arm V, on which the same is held, upward, causing the arm W to press upward the spindle V thereby separating the jaws V and V The jaws remain separated until the rack has completed its movement in the direction of the arrowg when the cam X slides off of the beveled shoulder \V" on the end of the track-bar \V, permittingthe springV to pressthespindle V and the arm \V downward. Then when the rack U moves in the inverse direction of the arrow g that is, in the direction of the arrow m', Fig. 1the bevel X of the cam X will be below the track-plate W, and thejaws will be clamped and held firmly together and will hold the. twine, in a manner that will be described hereinafter. It was necessary to describe this operation of the jaws before proceeding, in order that the further formation of the knot might be fully understood. Assuming that the parts are still in the position shown in Fig. at, we will now examine Figs. 12 and 13. The separated jaws V and V are revolved a secondv time, and the parts E of the twine, Fig. 4, are passed in between said jaws, which revolve, and by the time they have completed an entire revolution and are brought into the position shown in Fig. 13 the bevel X has run off of the track W* and'off over the bevel shoulder NV of the same, as mentioned above, thus permitting the spring V to force the jaws together, whereby the crossed ends of the twine are securely clamped. Then the lever Y moves in the in verse direction of the arrow a Fig. 5that is, the book 0 on the end of the-rod t, which was in the position it had in Fig. 12, moves out of said position, and the hook Y on the end of the lever Y moves in the direction of the arrow at, Fig. 4, and the prongs of the hook Y carry the part E of the twine againstthe lugs Z Z and against the knife Z, as shown in Fig. 13, whereby the twine is cut. Thencedle brings down the twine around the bundle with the part for the hand between the needle and the knotter. The knotter then starts, with thejaws open, catches both strands of the twine, draws the part to be carried to thelug 1 3 across the hooked rod 0 between the upwardlyturned point that catches the twine and the lug r s, and makes one revolution and stops. The hooked rod 0 at once starts the hook, catches both strands, and carries them over to the lug 9' s and holds them. Simultaneously with the starting of the hooked rod 0 theholder 3 releases the cut end of the twine, the sharp point of the holder y passes between the needle and the twine in the needle, afterward to catch, cut, and hold the end thereof for the new band as the parts return to place. The twine is sufficiently elevated while held within the lug a s by the slightly-upturned portion of the rod 0 near its hook to allow the lower jaw of the knotter to pass under the twine. As soon as the twine is secured in the upright groove of the lug 1* s by the hooked rod 0, the knotter again starts and completes its forward movement, the lower jaw passing under the twine as it is held in thclugrsby the hooked rod 0,and the upper jaw passingabove the twine, the jaws then snapping together upon the twine. The hooked rod 0 and the lever 7 at once go back to place, the lever 3 carrying with it the twinein the needleback to the knife, where it is out, and the end belonging to the needle is held for the new hand, both ends of the twine being then free to be pulled from the knotter. Immediately after this the ejector is operated in the manner described above and ejects the bundle, whereby the loop 11*, Fig. 14, is pulled from off thejaws V and Vithe needle D being raised iminediately after the bundle has been ejected.

As stated above, the grain forced down by the tines B presses the compressor and trip F in the direction of the arrow 0 after a certain quantity of grain has been forced between the arm 0 and said compressor and trip-arm. By this movement of the ejector the cam H is forced upward and the entire machine is started by the shifting of the sleeve I caused by the above-described movement ofthe camarm H and the consequent rotary motion of the shaft H. After the bundle has been ejected the cam H swings downand the spring H throws the lower end of the lever I-l outward, thereby swinging the prong H downward. The bevel of lug H strikes the lever I and forces the same to the left, Fig. 3, thereby engaging the clutch collar I with the clutch collar 1, whereby the shaft D is revolved and the other parts are put out of operation. The tines begin to force down the grain and the other parts remain stationary until the quantity of grain forced down is sufficient to swing the compressor and trip F in the direction of the arrow 0 such a distance as to cause the cam G to raise the cainarin H where the parts are brought into operation, as set forth before.
